ABSTRACT:
Methods and systems for processing signals in a receiver are disclosed herein and may include generating a plurality of chip-rate synchronously sampled signals utilizing a plurality of received clusters. At least a portion of the generated plurality of chip-rate synchronously sampled signals may be simultaneously equalized in time domain and in spatial domain. The equalization may be based on a plurality of weight values calculated for the plurality of received clusters. The weight values may be iteratively computed utilizing a time-based adaptation method, such as a conjugate gradient (CG) search. The equalized portion of the generated plurality of chip-rate synchronously sampled signals may be added to generate a total equalized signal. The total equalized signal may be demodulated to generate a demodulated signal. At least one convolutional code and/or turbo code within the demodulated signal may be decoded.
